Abstract

Warna kulit buah buah cabai rawit (Capsicum Frutescens L.) merupakan salah satu indikator dari kematangan buah. Visible/near infrared (Vis/NIR) spectroscopy merupakan teknologi alternatif untuk memprediksi warna kulit buah yang dikombinasikan dengan partial least square regression (PLSR). Penelitian ini bertujuan untuk memprediksi warna kulit buah cabai rawit menggunakan Vis/NIR spectroscopy. Analisis di Laboratorium Hortikultura, Fakultas Pertanian, Universitas Padj+!adjaran. Sampel yang digunakan yaitu buah cabai rawit var. Domba. Sampel dibagi ke dalam 3 grup, buah cabai rawit hijau, oranye, dan merah. Spectrometer yang digunakan yaitu NirVana AG410 dengan panjang gelombang 300-1065 nm dengan interval 3 nm. Semua data absorban dikoreksi dengan menggunakan metode prapengolahan spektra multiplicative scatter correction (MSC), orthogonal signal correction (OSC), dan standard normal variate (SNV). Hasil penelitian menunjukkan bahwa prapengolahan spektra terbaik untuk memprediksi L*dan b* pada buah cabai rawit yaitu PLSR+OSC sedangkan a* yaitu PLSR+SNV. Nilai akurasi L* dengan OSC yaitu R kalibrasi = 0,99 dan b* dengan OSC yaitu R kalibrasi = 0,76. Akurasi pada a* dengan SNV menghasilkan R kalibrasi = 0.99. Penelitian ini membuktikan bahwa Vis/NIR spectroscopy dan PLSR memiliki akurasi yang tinggi dan dapat digunakan untuk memprediksi warna kulit buah cabai rawit.Application of VIS/NIR spectroscopy and partial least square regression for estimation of skin color in cayenne pepper fruitThe skin fruit color of cayenne pepper (Capsicum Frutescens L.) is one of indicators of fruit maturity.

Abstract

Enhancement of productivity of potato plants grown on poor-P soil such as Inceptisols due to application of arbuscular mycorrhizal fungi (AMF) has been acknowledged. However, whether this AMF improved the quality of potato tubers is still need further investigation. This study was conducted to evaluate the effectiveness of AMF in enhancing potato quality and determine whether the addition of compost and biochar to soil can support the productivity of this biofertilizer in enhancing the nutrient content in the tubers of potato plant. Screen house experiment was set up in factorial design with treatments were organic matter types (compost and compost plus biochar), and application of arbuscular mycorrhiza (without and with AMF consisted of Glomus sp. and Gigaspora sp.). Results of experiment showed that there was no interaction effect between organic matter and AMF on quality of potato tubers, however, the individual treatment especially AMF  increased the content of protein and lipid of potato tubers. Biochar that added to soil with compost was also increased the lipid content of potato tubers. This finding showed that AMF application in potato production grown in poor P-soil was not only increased the yield of potato, but also increased the quality of potato tubers.

Abstract

This research aimed to study the addition of ameliorant material in the soil to increase fertility rates, especially for potato plants grown at the height of 750 m above sea level. The experiments were conducted on medium plains 750 m above sea level in the Jatinangor area, Indonesia, with land type Incepticol. The composition of ameliorant consists of Cattle manure, biochar from coconut shells, and dolomite. The seeds of the potatoes used are relatively good varietal when cultivated in a medium plain. The design of the environment used is the group’s random draft repeated three times, the treatment design consists of K0: control; K1: Cattle manure 10 Mg ha-1; K2: Cattle manure 20 Mg ha-1; K3: Cattle manure 8 Mg ha-1, dolomite 1 Mg ha-1, 1 Mg ha-1 biochar; K4: Cattle manure 16 Mg ha-1, dolomite 2 Mg ha-1, 2-Mg biochar ha-1, K5: Cattle manure 8 Mg ha-1, dolomite 2 Mg ha-1; K6: Cattle manure 16 Mg ha-1, dolomite 4 Mg ha-1; K7: Cattle manure 8 Mg ha-1, biochar 2 Mg ha-1; K8: Cattle manure 16 Mg ha-1, biochar 4 Mg ha-1. Results showed that the composition and dose of ameliorant could increase the value of soil pH but have not improved the C/N ratio and absorption of phosphorus plants. The best result was obtained from the composition treatment of 16 Mg ha-1 Cattle manure, 2 Mg ha-1 dolomite, and 2 Mg ha-1 biochar. Soil pH is capable of increased by 16.83%, and the size of the potato bulbs of Class L (450-550 mm) amounted to 35, 11%, size M (350-450 mm) by 25.89%, and size S (200-350 mm) amounting to 34.37% when compared with controls.

Abstract

The quality component measurement of horticultural products becomes more important to achieve better quality products also to obtain uniform product. Recently, measurement by non-destructive methods turns out to be more needed, because consumers become more selective and demand producers to develop a quick, effective and accurate quality assessment system. Near Infrared Spectroscopy (NIRS) can measure plant contents quickly, relatively economical in a bigger scale, and importantly non-destructive. The measurement of quality components of green bitter gourd, such as firmness, water content, total soluble solid, and color, are important but have not been widely conducted. This research was conducted from June to August 2013 at Post Harvest Laboratory, Faculty of Agriculture, Padjadjaran University, Sumedang, Indonesia with PLS regression modeling method. The results show R-value and standard error of 0.91 and 0.47 for water content, 0.93 and 1.03 for firmness, and 0.95 and 0.49 for a* value of fruit color.

Abstract

Efforts to intensify oil palm (Elaeis guineensis Jacq.) are needed to increase productivity close to the actual production potential of oil palm crops. The productivity and growth of oil palm is partly controlled by the relationship between the top of the plant (the leaf) and the bottom of the plant (root). This study aims to find out the effect of root pruning and the number of fronds on the growth, production and quality of oil palm products. The research was conducted for 12 months from February 2018 to January 2019 in gardens owned by the community of Petapahan Village, Tapung District of Kampar Regency, Riau. The research was conducted experimentally using split plot design which is grouped based on different plant age (5 years, 10 years and 15 years). The main plot is the pruning of oil palm, Normal, Light, and Heavy fronds. The plot is trimming the roots of oil palm 75%, 50% and 25%. The results showed that root pruning and the number of fronds did not affect the interaction of observational premeters. Pruning the roots independently gives a noticeable influence on the content of mesocarp oil. Self-trimming of the fronds has a real effect on the total increase in oil. Plant life has a noticeable effect on enhancement, total oil, mesocarp oil and free fatty acids.

Abstract

Lidah buaya mengandung polisakarida (glukomannan), antimikroba dan anti-inflammattory sehingga bisa digunakan sebagai bahan penyalut edibel (edible Coating). Penyalut gel lidah buaya lebih aman untuk kesehatan karena bersifat alami, tidak berwarna, tidak berbau, tidak mempengaruhi rasa, serta aman bagi lingkungan. Gel lidah buaya (GLB) mengandung bahan bioaktif yang berguna bagi kesehatan sehingga jika digunakan sebagai penyalut dapat menambah khasiat buah yang disalut. Bagian dalam lidah buaya berbentuk gel sehingga mudah diaplikasikan sebagai penyalut edibel. Akan tetapi, kendalanya gel lidah buaya mudah berubah konsistensinya sehingga untuk mempertahankannya harus ditambahkan bahan lain seperti gliserol. Penelitian ini bertujuan untuk mengetahui konsentrasi gliserol yang tepat pada penyalut gel lidah buaya agar mendapatkan karakteristik penyalut yang baik. Metode penelitian yang digunakan adalah metode analisis deskriptif. Percobaan dibagi 3 bagian, percobaan I bertujuan untuk mengetahui rasa GLB yang tepat, terdiri dari 5 perlakuan konsentrasi gliserol (0%, 0,5%, 1%, 2%, dan 3%), percoban II bertujuan untuk mendapatkan film GLB terbaik, terdiri dari 2 perlakuan konsentrasi gliserol (0,5% dan 1%), dan Percobaan III bertujuan untuk mengetahui daya lekat pada buah stroberi, terdiri dari konsentrasi gliserol (0,5% dan 1%). Penelitian dilaksanakan di Laboratorium Teknologi Pangan, Fakultas Teknologi Industri Pertanian, Universitas Padjadjaran, Jatinangor. Hasil penelitian I mendapatkan gel lidah buaya yang ditambahkan konsentrasi gliserol  0,5% dan 1 % tidak menimbulkan rasa pahit.

Abstract

Produktivitas cabai merah besar (Capsicum annuum L.) di Indonesia tahun 2019 sebesar 8,62 ton/ha dimana angka tersebut masih jauh di bawah potensi produktivitasnya (20-30 ton/ha). Angka produktivitas tersebut dapat ditingkatkan dengan pemupukan yang tepat. Controlled Release Fertilizer (CRF) merupakan pupuk yang dikembangkan untuk menyediakan nutrisi dalam kurun waktu lebih lama dan konsisten dengan kebutuhan nutrisi fisiologis tanaman. Tujuan dari penelitian ini adalah untuk mengetahui pengaruh CRF terhadap pertumbuhan dan hasil tanaman cabai merah besar. Penelitian ini dilaksanakan pada bulan Februari-Juni 2022 pada kebun percobaan di Bale Tatanen, Universitas Padjadjaran. Penelitian dilaksanakan menggunakan Rancangan Acak Kelompok (RAK) yang terdiri dari enam perlakuan dan empat ulangan, yaitu: campuran pupuk tunggal (300 kg/ha Urea, 200 kg/ha TSP, dan 200 kg/ha KCl), NPK konvensional 300 kg/ha, CRF 2 240 kg/ha, CRF 2 300 kg/ha, CRF 3 240 kg/ha, dan CRF 3 300 kg/ha. Hasil penelitian menunjukkan pengaplikasian CRF memberikan pertumbuhan dan hasil tanaman cabai yang lebih baik dibandingkan dengan campuran pupuk tunggal dan pupuk NPK konvensional dilihat dari tinggi tanaman, diameter batang, indeks klorofil daun, jumlah buah cabai per tanaman, dan bobot buah cabai per tanaman namun tidak menunjukkan perbedaan signifikan untuk panjang dan lebar daun, bobot per buah cabai, serta panjang dan diameter buah cabai. Perlakuan yang memberikan pengaruh terbaik adalah pupuk CRF 2 dosis 300 kg/ha.

Abstract

Potatoes are the third most consumed food in Indonesia. The availability of high-quality potato tuber seeds is still low which affects potato production. Potato planting in the highlands is limited, so it needs to be expanded into medium lands. The modification that can increase the production of G0 potato tuber seeds on medium lands is the use of biochar and retardant. The purpose of this research was to determine the composition of biochar and the type of retardant to increase the G0 tuber seed yield of potato cv Medians in the medium lands of Jatinangor. The research was conducted from August 2022 to February 2023 at the Station Ciparanje, Jatinangor, Faculty of Agriculture, Universitas Padjadjaran. The experiment used Factorial Randomized Block Design (RBD). The first factor was the biochar compositions: b1 (100% compost), b2 (80% compost + 20% rice husk biochar), b3 (80% compost + 20% coconut shell biochar), and b4 (80% compost + 10% biochar husk rice + 10% coconut shell biochar). The second factor was the retardant type: r1 (without retardant), r2 (100 ppm paclobutrazol), and r3 (100 ppm prohexadione-Ca). The experimental results showed that there was no interaction effect of biochar compositions and retardant type on the growth and yield of G0 potato tuber seeds. Treatment of 80% compost + 20% coconut shell biochar suppressed plant height but increased the number of tubers. Treatment of 100 ppm paclobutrazol resulted in lower plant height but total chlorophyll content, percentage of stolon forming tubers, the number of tubers, and tuber weight per plant were higher compared to treatments without retardant and with 100 ppm prohexadione-Ca.
